I think going the re-enactor way is a positive step. It may not change anything but on the other hand it might. At the very least it sounds better. For example if I was asked what hobbies do I do, saying that I participate in military style re-enactions sounds a hole lot more mature and credible than to say, I play airsoft.
That and the fact that so many stores now sell the softair products, which inevitably get confused with airsoft by the public. I think getting away from the term airsoft will help further our sports life.
Using the terms re-enactors or as Brian stated on the other thread, re-creators would be the way to go.
At any rate this looks like a positive direction for the sport.
If they take away the toy guns from law abiding citizens, sooner or later, only the criminals will have the really neat toys.
